Typically in these cases, any lender will require two years of U.S. tax transcripts (returns) before issuing a mortgage... however, depending on your prior working history, there may be a local bank or credit union that would possibly be able to pre-approve you for a mortgage.
One that comes to mind is "Macomb Schools and Government Credit Union"; you can google them for the closest branch, and either apply online or set up a face-to-face meeting.
Hope this helps!

It is a good idea to wait for few months and you get stabilized. Most lenders would need 2 year USA working history. Talk to few mortgage member and see what they can do for you.
